Enzymes are natural substances that speed up and regulate metabolic reactions in the body. Each enzyme has a unique mission, as it binds specifically to a specific substrate and catalyzes specific reactions. Enzymes are one of the most important active molecules in the body. They play an important role primarily in the body's defenses, where they balance the activation and inhibition of immune responses with which the body reacts to pathogens, injuries or harmful environmental influences. Enzymes also play a role in the body's normal metabolic processes, such as digestion, respiration, etc.
